Fossils in limestone.

In others, a rich fossil record accumulated over millions of years. Fossils of our earliest ancestors have only been found in Africa, especially in the Rift Valleys of East Africa and in limestone caves in South Africa. On other continents, our ancestors’ fossils are mostly less than about one million years old.

That said, fossil specimens in metamorphic rock are vanishingly rare and notable in even museum-grade collections. These are usually the result of some freak one-in-a-billion occurrence. For the most part, however, it can be assumed that 99.999% of fossils on the planet are contained in sedimentary stones.Two deposits of limestone known to paleontologists as the Helderberg Group and the Onandaga Limestone were formed in the inland sea. Marine life was still the dominant form of life, and trilobites were still abundant. ... Among the fossils is the oldest known flowering plant specimen: a 90 million-year-old cluster of tiny oak flowers.Sedimentary rocks are formed on or near the Earth’s surface, in contrast to metamorphic and igneous rocks, which are formed deep within the Earth.

Erosion and weathering include …Mar 28, 2023 · Overall, out of all of the separate subtypes of sedimentary rock, fossils are most abundant in shale, sandstone and limestone, though they also appear in conglomerates and breccias. Shale With fragments around 0.002 to 0.05 millimeters across, this type of sedimentary stone can preserve the traces of ancient animals and plants in incredible detail. The park’s 425-million-year-old shale and limestone rocks contain numerous marine fossils and are among the oldest bedrock exposures in Indiana.
